History

In Mobile Suit Gundam, he was shown to be an intelligent, good-natured man whereas in the Mobile Suit Gundam: The Origin version, he is portrayed as a paranoid old man entrenched in hatred of the Zabi family.

In the original TV series Jimba is endearingly referred to as "Old Man" by Sayla Mass. In The Origin, Jimba Ral constantly reminded Casval of the Zabi family's betrayal of the Deikuns, with Artesia hating him for this. After narrowly escaping an attempt on their lives by assassins (in which Jimba Ral was stabbed to death), they fled to Texas Colony.
